HERE'S AN IRONIC BIT OF HISTORY FOR ME: BACK IN FEBRUARY AND MARCH of 2001, I wrote a two-part series of columns titled SDSF/ISPF Primer Part 1 and Part 2. The opening paragraph of Part 1 read: Slowly, almost imperceptibly, I have been converted to an SDSF fan. I used to be a dyed-in-the-wool IOF fan.

Now, I have reverted back to using IOF. I really don't have much of a choice in which JES2 spool browser I use. It is decided for me by the installations where I ply my trade. And right now, my primary location uses IOF from Triangle Systems as their JES2 spool interface.
